Introduction to Technical Analysis is an investing concept used to improve decisions on allocation, risk control, and position sizing in real portfolios.

FAQs
Technical analysis is most reliable as a timing and confirmation tool. Momentum signals and trend confirmation have statistical validity across large samples. Where it breaks down is predicting fundamental changes — price cannot tell you when earnings will deteriorate.
No single indicator is universally best. RSI is most reliable for divergence signals. Moving averages are best for trend confirmation. Volume is the most underused — price moves without volume confirmation fail far more often.
AIQ incorporates momentum as one of its four scoring factors, measuring how a stock trends relative to its market and sector peers on a risk-adjusted basis. Strong relative momentum pushes the AIQ Score toward Buy; deteriorating momentum pushes it lower.
