The Nasdaq fell today as technology stocks tumbled on the back of rising bond yields and anxiety over semiconductor supply constraints. The weakness hit the sector ahead of Nvidia's earnings announcement, one of the most closely watched corporate results on Wall Street.

Bond yields climbed higher, making government debt more attractive relative to growth stocks. Tech companies, which rely heavily on cheap borrowing and generate most of their value from distant future earnings, tend to suffer when bond yields rise. The 10-year Treasury yield and shorter-term rates both moved higher, pressuring investors to reassess their portfolios.

Semiconductor supply concerns added to the selloff. Investors worry about the ability of chipmakers to meet surging global demand, particularly as artificial intelligence applications expand. Any hint of production bottlenecks or logistics delays can rattle the entire tech ecosystem, from smartphone makers to data center operators.

Nvidia stands at the center of this discussion. The graphics processing unit giant reports earnings soon, and traders expect the results will influence how the market views the broader chip industry. A weak forecast or cautious guidance could extend today's losses. A strong report might stabilize tech stocks.

For ordinary investors holding technology stocks through index funds or individual holdings, today's action serves as a reminder that interest rate movements drive valuations. When bond yields rise, the present value of future cash flows shrinks. This mechanic hits growth stocks harder than mature companies that generate profits now.

The supply chain concerns matter too. They suggest that even robust demand cannot guarantee smooth execution. Companies reporting delays or higher costs could disappoint investors counting on uninterrupted growth.

Retail investors should monitor Nvidia's upcoming results closely. The company's guidance will signal whether chip supply constraints are temporary or longer-lasting. If Nvidia sounds optimistic, it may restore confidence in the tech sector and lift the Nasdaq higher. If management sounds defensive, expect continued pressure on growth stocks until
