Analysis of institutional investor activity showed that foreign investors bought 11,000 shares, investment trusts purchased 652 shares, and proprietary traders acquired 2,501 shares on the previous day. Financial analysts recommend that retail investors observe a period of weak consolidation, noting that technical indicators show bearish signals. They advise against attempting to catch the bottom and suggest waiting for a stronger technical structure before entering the market.

For retail investors, it is best to remain on the sidelines at this stage and not try to bottom-fish too early. Wait until the technical structure strengthens before operating.
