This week's Your Weekly Review list sends a number of mixed signals. Optimists might see the bevy of stocks in bases or pressing to new highs. Pessimists are likely to focus on the ranks of sharp, heavy volume reversals. The most prevalent chart action this week saw stocks backing off after hitting new or at least 52-week highs. Most backed away slowly, in soft volume, sending no alarming signals. Bucyrus International (BUCY), Ulta Salon Cosmetics
