I actually looked into this. Yesterday, the Nasdaq hit its 10th consecutive day of gains. Historically, a 10+ consecutive day winning streak on NQ has happened once every 3–4y on average over the full history for the market....and in the modern era (last 25y) it's closer to once every 5–7y The last two occurrences were in Nov 2021 (post COVID) which served as a local top for the parabolic post-covid stimulus rally due to inflation & QT....while in July 2009 (post GFC) which progressed to a long secular bull market due to a highly accommodative fed policy after grossly oversold conditions.(CryptoCondom)
