Review today's trading

Bought one lot of Bubble at 240.2 at yesterday's close, set take-profit at 248.6 (planned for day trading). Today, it hit exactly at the high of 248.6 and sold, then bought back at 244.2 at the close. Bubble is a fateful stock indeed. Bought back 600 shares of Chifeng Gold at 28.15 yesterday, set 29.4 today, but the high was only 29.35, so no deal. Thinking that the Hang Seng Tech has stabilized, bought 600 shares in two batches at 118 and 117.2, planning to try mid-to-short term with a stop-loss. On 6/4, bought TSL at 328 and set a stop-loss at 322 on 6/5, which triggered a full liquidation. Although it was an extremely low position, it plunged into the abyss that day—close call! Last night, LULU gave me another lesson on not setting a stop-loss!!! The Q1 earnings missed expectations, leading to a 22% plunge. Fortunately, the position was only 2%. Today, set stop-losses for all other low positions.
