The SIG quant trading team is giving a special recommendation for QCOM.

QCOM Trading Strategy for September 15 to September 19:

The weekly chart shows a strong bullish trend, and the daily chart indicates the main upward move has started.

To avoid short sellers stepping in, we’re not disclosing the return rate for now.

The announcement from the State Administration for Market Regulation approving Nvidia’s acquisition of Mellanox Technologies with restrictive conditions is positive for QCOM and other memory chip makers, supporting market order growth.

As AI shifts from training to inference and edge devices, demand for high-capacity memory is heating up, and supply is tightening. Memory chip manufacturers have notified customers that all quotes for DDR4, DDR5, LPDDR4, and LPDDR5 products are suspended for a week, and prices may rise 20%–30%. This move impacts not only consumer and industrial memory products but also automotive electronics, where price hikes are expected to reach as high as 70%. Industry analysts say Micron’s decision shows that with the rapid rise of AI inference, high-capacity memory products are undergoing structural changes, with demand surging significantly
