在当今瞬息万变的金融市场中，投资人们常用的金融工具种类多不胜数，每一种都有其特定的风险和回报。究竟投资人常用的金融工具数量是多少？这成为了众多投资者心中一个备受关注且引起好奇心理的问题。

首先要明确，在现代金融市场上，各种类型的金融产品层出不穷。从传统股票、债券、期货到新兴数字货币、衍生品等等，涵盖了范围极广泛。而针对个体投资者来说，则更显复杂：除了直接买卖证券外，还可以通过基金、信托计划、保险产品等方式进行间接投资；此外还有银行存款、黄金珠宝等非证券类别可供选择。

其中最为普遍使用且较容易获取信息与交易渠道相对开放透明之准流动性标准化商品包括但并不限于：股票（含A股/B股/港美国ADR）、ETF(Exchange Traded Fund) 以及指数基金; 债务品(Bond, 含公司债公募私募); 外汇(Forex), 能源原料 (Commodity)，房地产物业 REITs 等大型板块领域能找得到很方便价格实时更新质量高低差异也比较小之正规化交易所或平台上被广泛应用。
