The **Relative Strength Index (RSI)** is a way to see if a share's price is going up or down too quickly. If it's above 70, it might be going up too fast and could come back down soon. Most of these companies have high RSI numbers, which could mean their prices might go down soon.

In simple terms, these companies did well recently, but some people think their share prices might drop soon because they've gone up a lot in a short time. Read from source...

Based on the provided information and stock prices mentioned, here are some points highlighting potential overbought conditions or inconsistencies:

1. **Olo Inc (OLO)**:
- The Relative Strength Index (RSI) value of 90.08 is considered highly overbought, indicating that Olo's stock price has risen sharply and may be due for a pullback.
- Despite the high RSI, the stock gained another 10.6% on Tuesday, suggesting irrational exuberance among investors.

2. **Couchbase Inc (BASE)**:
- While not as extreme as OLO, BASE also has an elevated RSI value of 78.49, indicating that the stock is becoming overbought.
- The company's share price has gained around 18% in the past month and is approaching its 52-week high. A slight pullback could be in order.

3. **BILL Holdings Inc (BILL)**:

These rapid gains and elevated RSI values could suggest emotional behavior among investors, as well as potential irrational arguments driving the stock prices. However, it's important to remember that:

- Individual stocks can continue to rise despite being considered overbought due to company-specific positive catalysts or market sentiment.
- Always conduct thorough research and consider multiple factors before making any investment decisions.
