I'll let my teammates try it out tomorrow. I feel the joy of AI democratization, where ideas can be turned into interactive products with a low barrier. I plan to make another one in the next few days, let me think about it first...Today's US stocks are also good. I'm planning to reduce some positions opportunistically. I did a simple calculation: four stocks per account, totaling 80%, leaving 20% for deepbuy. I calculated the target number of shares and the base position for each stock. For example, for VOO, I plan to buy 50 shares (5-5-7-8-10-15) and reduce positions when the price rises, with a base position of 35 shares. If there's a 20% plunge, I'll use the 20% public position to top up. The regular position should be no less than 50% and no more than 80%.Currently, Longbridge has selected UNH, meta, Goog, NVDA. For the long term, keeping goog and Nvda is sufficient. IB currently has Msft, BRKB, Voo, and QQQ; for the long term, keeping brkb, Voo, and QQQ is sufficient.Take it slow. Once profitable, the subsequent 10% of the position can follow friends for short-term trades. 90% of the position is concentrated on core long-term large-cap stocks.I'm not planning to add high-risk investments this year; I feel my skill level can't handle them. I will gradually add some low-risk financial products, mainly large-denomination certificates of deposit that can be redeemed early, money market funds, and bond funds, focusing on safety and flexibility. I'm building a 15-year living expense fund pool (mainly considering this is enough time to raise the kid into a workhorse). Then, my stock and fund venture, which currently consists of these US large-cap stocks + broad-based funds, along with domestic dividend stocks + gold + regular investments in Nasdaq and S&P 500 ETFs (both on and off the exchange), as long as the Earth doesn't explode, over a 10-year cycle, it should always 📈, right?Finally, study hard, work seriously, supporting myself shouldn't be that difficult, right? I don't eat much and my living standards aren't high.Hahahaha, after calculating this way, the safety margin still seems reliable.Time to sleep. Health is the capital of revolution.

In the end, I invested - **闯荡美利坚** (2026-04-01T00:46:24.000Z): Hong Kong insurance belongs to what big brother said "building future cash flow". - **慢慢长大的南瓜** (2026-04-01T14:49:59.000Z): Boss has a lot of money.
