Buybacks are useless for small, growing companies. For something on the pinksheets, they scream SCAM as many a company say they put a buyback program in place with no intention to ever buyback shares. People know this. If VTSI did actually buyback any shares, I think you would only see a temporary gain in PPS only to have it fall in low volume periods like it does between earnings releases.
Spend the money to be SEC compliant, uplist, increase marketing/sales, hire more people (i.e. grow the business). That's where sustainable PPS appreciation will occur and attract the institutional buyers, IMO.
