I prefer to see the corpse twitch once or twice before I re-issue his social security number. TZA is kind of a limbo contest isn't it: New all-time lows and no visible support of any kind that I can see. If I had the burning itch to go long, I'd probably be buying some puts along with it just in case. It's a more likely candidate for a short on a rally in my opinion. My $0.02
If there is absolute support then it's time to go all into TYH, guess that's good for another $150+ to the upside. When a trade becomes to easy it's time to take notice of what's coming.
