Why is 'Full-Time Investing' Painful?

1. The 'Annual Goal' Trap of Full-Time Investing

Full-time investors often set an annual return target of '30%', and this pressure can lead to two major fatal mistakes:

Forced Speculation

To achieve the goal, they have to chase hotspots and trade frequently. For example, during the new energy speculation in 2021, countless full-time investors bought high, ultimately suffering significant losses;

Imbalanced Mindset

Short-term stock price fluctuations can amplify anxiety. When Tencent's stock price halved in 2022, full-time investors might be forced to sell at a loss due to mortgage pressure, while those investing spare money can calmly increase their positions.

2. The 'Anti-Fragile' Advantage of Spare Money Investment

Duan Yongping suggests 'investing spare money that won't be life-threatening', which essentially builds an 'investment safety margin':

Pressure-Free Decision Making

Investing 20% of monthly surplus means that even if you lose 50%, it won't affect your life. For example, an office worker earning 8000 yuan can invest 1600 yuan in index funds, and when the market drops, they can 'buy more as it falls';

The Premise of Time Compounding

Spare money investment allows you to truly practice 'long-term holding', such as a programmer who invested spare money in BTC with an annualized return of 80%, far exceeding the performance of full-time investors who trade frequently.
