First tip: don't trade just based on someone's advice. Do your own research to make sure you agree with them. This doesn't mean to ignore them, just not to blindly follow.
I'll start with HDY: avoid it. My reason is simple, it just doesn't have enough volume. This makes it more prone to quick jumps and less liquidity. If nobody's trading it when it drops, you'll never get out.
DYN: Bearish outlook. While it's at a several year high, it looks like it's currently running on fumes. Also, it's got a very low value, which leaves litte room for movement one way or the other. I wouldn't touch it, personally. There's bigger fish to fry.
PFE: It looks like it'll break one way or another soon, but cant' tell which. Earnings on July 19th will likely be a driving force, and chart patterns suggest that it could go either up or down. I'd not touch stock on it, 'cause you have to pick sides. It might be feasible to try a 27.5 straddle with September or December options, but the stock'll have to move a few points in either direction to make it profitable; it's not been particularly volatile in the last year though, so the odds of that happening are probably low. Also, 28 has been a point of resistance in the past, so breaking it will require a bit of a push...
Overall: find something more attractive :icon_wink:
