      "body": "Hello again, today I want to share with you a portfolio investment I did with cryptocurrencies. So let start with the basics… What is an investment portfolio? An investment portfolio is a mix of assets like stocks or bonds or another kind of financial asset that has as an objective to minimize risk and maximize returns through diversification.\n\nThis is achieved by diversifying risk, this mean that you assign your money in different assets and not only in one asset which could be very risky. In other words, diversification allows the investor to reduce risk without reducing the portfolio expected return.\n\nAll these concepts come from what is called the portfolio perspective which refers to evaluating individual investments by their contribution to the risk and return of an investor’s portfolio. \n\nSome other concepts you may want to be related to are: \n\n•\tVariance: According to Investopedia, the variance is a measurement of the spread between numbers in a data set. The variance measures how far each number in the set is from the mean. \n\n•\tStandard Deviation: Is the square root of the variance and also measures risk or volatility.\n\n•\tCovariance: Is a measure of how 2 assets move together. It ranges from negative infinity to positive infinity.\n\n•\tCorrelation Coefficient: It is the result of dividing the covariance of 2 assets by the product of the standard deviations of those 2 assets. It ranges form -1 to +1. A correlation of -1 means that the assets have perfect negative correlation which means that the movement of 1 asset results in the exact opposite proportional movement in the other asset. Vice versa for a result of +1 that would be a perfect positive correlation of the 2 assets. \n\n•\tPortfolio Expected Return: Is the expected return of a portfolio taking into account the weights and the returns of each one of the assets that conform the portfolio. \n\nThe formula for the portfolio expected return is the following:\n\n ![protfolio Er.png](https://steemitimages.com/DQmb3a7WVw1t4XLQ2yMXXsuV96gMxdBuZm5J5j4ySXXxdxj/protfolio%20Er.png)\n\nThe formula for the Variance of the portfolio of 2 assets is the following:\n\n ![Captura de pantalla 2018-03-14 a las 12.57.59 a.m..png](https://steemitimages.com/DQmaucebaAZgBccHfR5zrooNAejNQKarWxNkM4F1ZBubMe5/Captura%20de%20pantalla%202018-03-14%20a%20las%2012.57.59%20a.m..png)\n\nwhere: \n\nW1: Weight of asset (1)\n(1)^2: Variance of asset (1)\nW2: Weight of asset (2)\n(2)^2: Variance of asset (2)\nCov1,2: Covariance of asset 1 and 2\n\nSo now that we have talked about some basic theory, I want to explain how I create this portfolio. The portfolio is composed by four cryptocurrencies: Ripple, Stellar, Litecoin and Transfercoin. \n \nFor this analysis I used the historical data of each of these 4 cryptocurrencies of 2 years (730 days) from March 4, 2016 to March 4, 2018. One of the reasons I chose these assets is because I needed to use the same data and not all the cryptocurrencies started at the same day or the same year so some are younger than others. \n\n ![Captura de pantalla 2018-03-14 a las 12.54.30 a.m..png](https://steemitimages.com/DQmQztkwoGfJG1oCxYwXWvMDuc1vsHBNUmTdHvu7QYy467W/Captura%20de%20pantalla%202018-03-14%20a%20las%2012.54.30%20a.m..png)\n\nAfter getting all the closing prices and their respective returns for the 730 days, I calculated the average daily return of each cryptocurrency and the standard deviation.\n\n ![Captura de pantalla 2018-03-14 a las 12.48.27 a.m..png](https://steemitimages.com/DQmeNooxp6qfy5zbAWZK3K6bZ1PDphaZFb2Yj4zLtxeqDsJ/Captura%20de%20pantalla%202018-03-14%20a%20las%2012.48.27%20a.m..png)\n*Remember that these are average daily returns.\n\nAfter calculating the returns, I calculated the Covariance for each one of the assets and the results were the followings:\n\n ![Captura de pantalla 2018-03-14 a las 12.50.48 a.m..png](https://steemitimages.com/DQmTtsLxwTR56L5RFZq59Wph8ubHfDdGAyZowqy8Wo9qxcC/Captura%20de%20pantalla%202018-03-14%20a%20las%2012.50.48%20a.m..png)\nNote: The covariance of the same asset is equal to the variance of that same asset.\n\nOnce I had these results I started to randomly assign the weights and the amounts of investment for each one of the cryptocurrencies in the portfolio in order to calculate the Expected Return of the Portfolio and the Variance.

      "body": "Hello again, today I want to share with you a portfolio investment I did with cryptocurrencies. So let start with the basics… What is an investment portfolio? An investment portfolio is a mix of assets like stocks or bonds or another kind of financial asset that has as an objective to minimize risk and maximize returns through diversification.\n\nThis is achieved by diversifying risk, this mean that you assign your money in different assets and not only in one asset which could be very risky. In other words, diversification allows the investor to reduce risk without reducing the portfolio expected return.\n\nAll these concepts come from what is called the portfolio perspective which refers to evaluating individual investments by their contribution to the risk and return of an investor’s portfolio. \n\nSome other concepts you may want to be related to are: \n\n•\tVariance: According to Investopedia, the variance is a measurement of the spread between numbers in a data set. The variance measures how far each number in the set is from the mean. \n\n•\tStandard Deviation: Is the square root of the variance and also measures risk or volatility.\n\n•\tCovariance: Is a measure of how 2 assets move together. It ranges from negative infinity to positive infinity.\n\n•\tCorrelation Coefficient: It is the result of dividing the covariance of 2 assets by the product of the standard deviations of those 2 assets. It ranges form -1 to +1. A correlation of -1 means that the assets have perfect negative correlation which means that the movement of 1 asset results in the exact opposite proportional movement in the other asset. Vice versa for a result of +1 that would be a perfect positive correlation of the 2 assets. \n\n•\tPortfolio Expected Return: Is the expected return of a portfolio taking into account the weights and the returns of each one of the assets that conform the portfolio. \n\nThe formula for the portfolio expected return is the following:\n\n ![protfolio Er.png](https://steemitimages.com/DQmb3a7WVw1t4XLQ2yMXXsuV96gMxdBuZm5J5j4ySXXxdxj/protfolio%20Er.png)\n\nThe formula for the Variance of the portfolio of 2 assets is the following:\n\n ![Captura de pantalla 2018-03-14 a las 12.57.59 a.m..png](https://steemitimages.com/DQmaucebaAZgBccHfR5zrooNAejNQKarWxNkM4F1ZBubMe5/Captura%20de%20pantalla%202018-03-14%20a%20las%2012.57.59%20a.m..png)\n\nwhere: \n\nW1: Weight of asset (1)\n(1)^2: Variance of asset (1)\nW2: Weight of asset (2)\n(2)^2: Variance of asset (2)\nCov1,2: Covariance of asset 1 and 2\n\nSo now that we have talked about some basic theory, I want to explain how I create this portfolio. The portfolio is composed by four cryptocurrencies: Ripple, Stellar, Litecoin and Transfercoin. \n \nFor this analysis I used the historical data of each of these 4 cryptocurrencies of 2 years (730 days) from March 4, 2016 to March 4, 2018.

I just finished my bachelor at Finance Management and have been searching for job these last couple of months. \n\nI learnt about this amazing webpage thanks to my friend of life @reversediabetes, he has been here for a couple of months now posting a lot of interesting things about a theory he has about how to stop diabetes and personally I thing is very amazing and interesting so you should go and follow his blog!\n\nI love to travel to different places, I love finance (obviously) and I love basketball. I could easily say these are my 3 passions in life. So when I decided to start my blog on Steemit I decided to do it about two of those three passions I have, finance and travel. \n\nRegarding the finance part, this blog is made with the only intention to inform and share my personal opinion about investing in cryptocurrencies through an investment portfolio or through daily trading using technical analysis.\n\nI sincerely hope you enjoy my posts and be helpful for you if you are trying to learn more about investment concepts or some technical analysis theory or you just want to read about my trips.\n\nHere is one of my latest trips I made and that I have enjoyed the most! (I'm the guy sitting on the edge and the red little point is my brother hahaha)\n\n![IMG_0658.jpg](https://steemitimages.com/DQmUUJZJ59NV2UQsLd3KhUdHAMvWGQ81VCMXutPkvrELQG7/IMG_0658.jpg)\n Torlltunga, Norway.\n\nThanks again!
