Why I bought BNS Holding

Yesterday, I bought less than 200 shares of BNS Holding for $12 a share. On July 19, shareholders will vote on a proposal to pay out $13.62 for partial shares in a 200:1 reverse split. Since there is a definitive proxy and since insiders control about 44% of the shares, the odds are very high that this transaction will go through. I put the odds at 95%. Since the shares traded at $12 a share just before the announcement, I'm getting a free option on the going-private transaction. My calculations based on the Kelly Criterion show that it would be rational to risk 93% of my funds on this investment. The worst case (a 5% chase the company falls to $0 instead of $12) would still be worth a 50% bet. By any standard, this is a good risk.

Thinking back on it now, I realize that I was a bit harsh on myself for buying Kaiser Group Holdings earlier this year. My arbitrage spreadsheet shows I estimated there to be a 75% the going-private transaction would occur. My purchase price implied a 14% chance. 75% was clearly too high in hindsight, but I still think 14% was a bit too low. Maybe 25 or 30% would have been accurate. In any case, the investment was well worth the minimal risk based on the Kelly Criterion. With relatively low odds and a high potential reward, I think I actually made a good decision even though I didn't get the desired outcome.
