Let us use a few examples to understand the topic.

Example #1

As per a report published on October 20, 2023, the Bull & Bear Indicator of the Bank of America indicated a strong buy signal. It signaled a highly bearish level at 1.9 from 2.2 while surpassing the benchmark of 2.0. It is so because when the bear indicator goes below 2.0, then the contrarian signal to buy riskier assets gets triggered. Past data since 2002 supports the signal, indicating that the buy signal lasts for 3 months whenever it triggers.

As per the Bank of America’s data made available recently, a record of $108.9 billion has been outflown. Furthermore, every November till January always sees a 6% rise in stock prices for the NASDAQ composite.

Thus, as per the Bank of America’s bull and bear indicator, a buying signal has been triggered that would help people analyze and take advantage.

All of a sudden, Emily observed a surge in buying orders for healthcare stocks, as indicated by a 20% increase in purchases from Los Angeles, California-based investment firms last week. Historically, since 2010, U.S. healthcare stocks have had a 15% median return for three months after this sign. Furthermore, the bullish sentiment aligned with the Q&P 500’s recent 10% upswing, despite intermittent market volatility since September.
