Well, this correction hasn't been helping much. As for the MULE trade, I find that you don't need to subscribe to crazy newsletters to find this kind of rumor. I use cnbc. It's practically free if you have schwab, but I've got spectrum cable and have it there too. It always starts as rumors, and the rumors that actually show up on cnbc become strong rumors. In fact, most of those rumors do end up in some kind of merger announcements.
Throughout the years, what I've learned is that most mergers below $15B will be nearly all cash acquisitions and are the ones that moves the stock prices the most. There are a few big ones that can move the stock prices of the seller, but nothing like those all cash deals. MULE was a close one, so it played more like a cash deal. I use the rumors on cnbc to pull up the seller and look for news on the deal. I'll look at the rumored price and calculate that with current price to see what kind of an advantage I might have. A lot of times I'll miss out because the deal came out as a surprise, but there are still many more where you actually have time to jump in before the deal closes. After the rumor is out, I usually have a couple days at best to get into the stock before actual news comes out and the stock explodes. In general, if the rumor comes out on Monday-Wednesday, then the actual report can occur that same week. If you are getting rumors towards the end of the week, then look for the actual deal on Sunday to Monday.
MULE was the most recent, but I've been in PNRA, PLKI, and STRP last year. And some like STRP will give you multiple days to jump in when there's a bidding war. My advice is never jump in too early. Wait for that early frenzy to die off, and it will. My position on MULE was slow, I initially took a small position after it slowed down and then added more throughout the day only because the rumors I read suggested the report would come out soon (as early as end of week).
