It is well known in crypto currency markets that when Bitcoin moves up or down the rest of the market follows, mostly. Principal component analysis (PCA) can help determine how much of the market movement is correlated. Some groups of coins such as Ethereum, NEO, and at times DASH and Monero have moved differently from Bitcoin. These different groups can be identified (to some degree) in the eigen vectors of the PCA. For each eigen vector, the amplitude coefficients show its dominance in the market at any given time. This analysis uses the covariance matrix of the normalized dataset (as plotted above). Please wait for the data to load, execute the analysis and view the results below.

Since crypo markets change dramatically, and only a short 3 month data window is followed here, comments are periodically moved from here the technical blog at statstec.ca. In PCA analysis, a centred version of the normalized data set can be rebuilt by multiplying the eigenvectors (EG listed in Appendix) by their amplitude scores (the curves 'a' above). Note that a negative EG1 coefficient multiplied by a negative amplitude score indicates price increase. In the plot above, the zero value of the amplitude curves represents a mean (sort of). From the results, typically over 90% of the information can be reconstructed with 4 eigenvectors. Also, EG1 represents typically about 80% of variations in the market. The coefficients of EG1 are all negative for every coin, except for Tether. It represents correlated market movements and perhaps indirectly money in the market.EG2 and E3 typically represents around 10% and 5% of variations in market, respectively. Here coins like NEM, and Binance, or Ethereum, NEO, and Stellar, are negatively correlated to Bitcoin and other coins. Amplitude curves 'a2' and 'a3' represent a certain proportion of money that moves toward or away from these coins to the others. (similar analysis applies to EG4).
