### 缓存策略架构
```
L1 缓存 (内存)
├─ TTL: <1s
├─ 容量: 热数据
└─ 命中时间: <1ms
↓
L2 缓存 (Redis)
├─ TTL: 1-3600s
├─ 容量: 频繁数据
└─ 命中时间: <100ms
↓
L3 缓存 (Redis persistent)
├─ TTL: 3600+s
├─ 容量: 参考数据
└─ 命中时间: <100ms

title="市盈率 (PE) 投资指南",

content="""PE比率是股票估值的重要指标。
计算公式:
PE = 股价 / 每股收益(EPS)
理解PE:
- PE反映投资者愿意为每1元利润支付的价格
- PE越低,股票相对便宜;PE越高,相对昂贵
判断标准:
- PE < 15:可能被低估,但需警惕陷阱
- PE 15-25:接近市场平均水平
- PE > 25:可能被高估,或市场对其有高增长预期
应用技巧:
1. 不同行业PE差异大,需要与同行业对比
2. 查看历史PE范围,判断当前位置
3. 结合PEG比率(PE/增长率)更准确
4. 关注动态PE vs 静态PE
注意事项:
- PE仅是参考指标,不能单独作为投资决策
- 需要考虑企业成长性和盈利质量
- 避免价值陷阱(便宜但没有理由便宜)""",

- ROE > 20%:优秀企业,持续值得关注
- ROE 15-20%:良好企业,符合巴菲特标准
- ROE 10-15%:正常企业,需观察趋势
- ROE < 10%:需要改善
应用技巧:
1. 查看ROE的5年趋势,更重要的是持续性和增长性
2. 与行业平均水平对比
3. 关注ROE的分解(利润率×资产周转率×杠杆)
4. 避免ROE虚高(通过高杠杆实现)

- 设定亏损达到初始投资的5-10%时止损
- 简单易行,适合初学者
2. 技术位止损:
- 在关键支撑位下方设置止损
- 更专业,需要技术分析能力
3. 时间止损:
- 持有时间超过预定期限仍未盈利则止损
- 适合有明确时间框架的投资
4. 趋势止损:
- 跌破重要趋势线时止损
- 需要判断趋势变化
止损纪律:
- 进场前就设定止损价格
- 严格执行,不要移动止损
- 记录止损原因,复盘学习
