An integrated early warning system for stock market turbulence

作者:

Highlights:

• Stock turbulence is identified by the SWARCH high volatility regime.

• Crisis cutoffs are dynamically determined by the two-peak method.

• The LSTM network predicts stock crises with a test-set accuracy of 96.4%.

• An average of 2.8 days forewarned period is achieved by the proposed EWS.
