I made the mistake of entering too early yestday at 6.99, but I took the chance to average my price down during the dip, bought large stake when it\'s below 6., so still came out with about 15% profit. Well, some profit is better than nothing. Due to the uncertainty involved, I don\'t want to hold a position for too long.

So far I am still holding a large position in C, with a small paper loss, but I may average it down if necessary.
=========================
To be conservative, let assume “about 15%” is 14.5%.

Selling at 6.75 with 14.5% gain => the average price is 5.8951965.

Yesterday’s low was 5.87. For those who trade often, you know how difficult to get the low even if you have a buy order higher than that. Again, to be conservative, let’s use 5.87.

Question:

For each share bought at 6.99, how many shares at 5.87 are needed to bring the average to 5.8951965?

43!
