Last Thursday, CNBC reported several times on AIG, saying that there were no shares available to short, and that the Bears were being squeezed. Geez, I guess! The stock was at about $47, up from $8 in early July.
Friday morning, they squeezed the shorts almost to $56, which was followed by a $10 selloff. Parabolic rallies usually don't end well, but they can inflict tremendous pain on the shorts if they don't get out of the way. Anyone shorting "because" AIG rallied 100% ... 200% ... got punished severely as the stock rallied 560%! Merciless!!
After the $10 selloff, giving the shorts at least some temporary relief, I got interested in the long side of AIG, but ONLY if I had solid technical reason for playing it. So I watched it, and here's what unfolded:

An Inverse H&S broke out, measuring back toward the morning highs, and then the channel, in yellow, formed. Ooo-oooo...
What I especially liked was the fact that the lows of the channel at Yellow #2, #4 and #6 were THREE successful restests of the neckline, constituting TRIPLE validated support. Lovely! If AIG could break out of The Channel to the upside, that would be a DOUBLE breakout (Inverse H&S and Channel), and the squeeze should be on again.
I got long at 49.87 with a mental stop below 49.28, the low of the Right Shoulder of the Inverse H&S. Right Shoulders "shouldn't" get taken out, and if they do, I'm not interested. Risk: $600. Targets were 50.90, the top of The Channel, and 51.90-ish, the measured move off a Channel breakout (high minus low, added to the breakout).
The channel broke out, but got only to 50.79, below the first target at 50.90. That ended up hurting my trade because I wanted to unload half my position there, but the stock came back toward my entry, and it was getting late in the game. I didn't want to hold overnight given the volatiility in this stock.
Late in the session, The Channel (seen in red here) looked to be morphing into a THIRD Bullish pattern, a Symmetrical Triangle, in white. What I didn't know, was if Data Point #4 (in yellow) already was in, or if there would be one more move down for Data Point #4 (in white), and there only was about an hour left in the session.
I decided that since I ju-u-ust had missed my 50.90 target, that might be all that I was going to get, which is why I said that it hurt my trade. If I had cashed in half the position up there, I could afford to get stopped out below 49.28 on the other half, and still come out of it with a gain. So, I raised my stop to "a break of the yellow trendline/anything below 50.00."
The yellow trendline got broken. 50.00 got broken, so I stopped it out for a very small gain. AIG put in White Data Point #4, at about 49.80, then broke out on BIG volume, and both targets got MADE.
Arrrrrrrrrrghh! LOL.
Gain: $75. Pitiful, but the amount isn't important. Having a plan and managing risk is what's important. I "coulda" had about $1,500 on the trade if I had kept my stop at 49.28, but I also "coulda" lost $600. My risk:reward was 1:2½, so I probably "shoulda" held, but we aren't always going to make the winning decision. That's all part of the game.
Accept it with dignity, and move on. Curses! Curses! Curses!
