GOOGL — factor decomposition (Technology)

How much of GOOGL's move over the window is systematic (market, XLK sector-excess, rate-excess via TLT) vs. idiosyncratic (stock-specific).

R² is 0.35 — a reasonably reliable fit; the betas and the split below are worth reading at face value.

Of GOOGL's +69.3pp move over this window, +41.7pp (60% of the total magnitude) is idiosyncratic — not explained by riding market, sector, or rate moves. The rest (+27.6pp) came from systematic exposure: market +27.6pp, sector +0.0pp, rate -0.0pp.
