I did have as many as many as 50,000 post-split shares at one time with a "paper" profit of over $500,000 when the stock was over $14. I sold off shares (not at the highest prices) to pay for a condo in Florida which I now call "Chateau Cyto." I took $300,000 in profits due to the timing of the condo purchase which turned out to be lucky timing. I added some shares today at 6.17 (also luck) and now am back up to 30,000 shares. I believe in the long-term opportunity CTSO offers and I want to have a meaningful position again.
Actually, the stocks in the index are NOT sold by the ETF manager. The ETF maintains its positions. It is not actively managed. If the individual stocks were sold it would no longer track the index. The only changes in positions by the ETF is when the index is readjusted as was just done to add or delete stocks.
