A Different Perspective

Lucapa Diamond shareholders are down 33% for the year, but the market itself is up 25%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 15% over the last half decade. We realise that Buffett has said investors should 'buy when there is blood on the streets', but we caution that investors should first be sure they are buying a high quality business. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
