November lived up to its name as a very good month for investors. World shares were up 9.3 per cent, the best return in three years. The S&P 500 in the US rallied 8.9 per cent and the local NZX 50 posted an impressive 5.3 per cent increase, the biggest monthly gains for both indices since July 2022. It wasn't just shares that had a great month, with conservative assets getting in on the action too. US bonds had their best month since 1985 (with a 4.5 per cent rise), while the NZX Investment Grade Corporate Bond Index posted a 2.7 per cent increase, the strongest since the index came into being in 2001. Why was November such a strong month, and what might determine whether this strength continues through to the end of the year?
