Which market inefficiencies did you spot?

My spot:

On March 10 2023, Silicon Valley Bank collapsed due to a bank run. SVB held a large number of long-term bonds. The market value of these bonds decreased significantly throughout 2022 and into 2023 as the Federal Reserve raised interest rates to cope with the inflation, causing unrealized losses on the portfolio. Higher interest rates also raised borrowing costs throughout the economy and some SVB clients started pulling money out to meet their liquidity needs. To raise cash to pay withdrawals by its depositors, SVB was forced to sell securities with big losses. The announcement of these losses caused a bank run the next day. The same month, Silvergate Bank and Signature Bank also went bankrupt.

These bankruptcies caused an overselling of bank stocks. For example, ING Bank ($INGA) (-0,73%) dropped about 23% in value. ING had a strong balance sheet and did not own a significant amount of long-term bonds. ING made a lot of profit from the interest margin of the cash stored by its customers. As the ECB raised the interest rates and ING was not planning on raising the interest rates for its customers, I expected the profits to increase significantly. Therefore, I bought ING Bank in March 2023 a profited +42%.
