I am invested in 56 companies as of May 5, 2015.
I will update this once a month, as that is the frequency of my trades. Daily and monthly market gyrations will obviously skew these figures, but this is not an exact science. The weights have been rounded up/down accordingly, so the total may not add up to a perfect 100%.
Total equities value as of May 5, 2015: $196,596.75
