Altair Nanotechnologies (ALTI) Spikes 16%

Altair Nanotechnologies (ALTI) spiked 16.6% today (02014.02.25) even though I don't know why. Volume was 5-times the trailing-3-month average. ALTI closed today (02014.02.25) at $5.83. ALTI 52-week range: $2.02 - $8.00. Our ALTI investment is nicely above water, but it's a small investment and it remains entrenched in the bottom third of the GDT::Portfolio.

[update::02014.02.26] 30 minutes into trading today and ALTI is up 12% of heavy volume (487,000 vs. 33,100). ALTI is at $6.53 after hitting an intra-day early morning high of $6.94. If there's news (and I suspect there is), I'm not aware of it.

[update::02014.02.27] ALTI closed yesterday (02014.02.26) at $5.98, up only 2.57%. Intra-day high was $6.98. Volume was 770,889, which according to the information I see on Yahoo! Finance is ~16% of the float. Again, if there's news, I don't know that it is.
