Just a gut feel after watching trading over the past week.
Bigger bids are appearing on the SLTOA side than SLT itself. It looks like this is where the accumulation is happening. Obviously this is a great show of confidence for SLT.
Also, did you notice Genelabs in the US? Up another 8% on the last day of trading to $1.90, its highest close in several months. Either related to the SLT/Genelabs announcement due shortly or a coincedence...
