1. 金融数据可视化
1.1. matplotlib
1.1.1. 沪深300走势图
注意:
- 数据,是使用我公开放在gitee上的csv文件,直接读取就能用。(ssl要加import,否则报错。)
- 中文,要加配置参数mpl
- mac和windows字体不同,mac可以用Arial Unicode MS,windows用SimHei
点评:
- 生成的图,没有动态交互效果。
- 如果只是想看趋势,这是很方便的方法,如果要细致查看图表细节,那最好用其他绘图包。

1.1.3. 收益率与风险

从下面绘制出来的图,我们能知道什么信息?
- 新能源,真的是毫无节操,收益率平均最低,而且波动还最大!
- 券商,等于就是白玩,所以如果要持有,一定一定要高抛低吸!
- 沪深300,中证500,医药这样的标的,长期肯定是能挣钱的!而且还不低,平均能到8%!!!
- 黄金,收益率好,且波动率低,but,通过课外只是可知,这是跟康波周期有关,只是这货的波动,可能是十几二十年这样为周期,还是少碰为好!一旦套牢,不知何时才能回来的那种。反正我是不看的。
1.1.4. 成交量与涨跌的关系

sh300["日收益率"] = round(sh300["close"].pct_change()*100,2) # 其实原数据已经有了,只是为了印证。
# 调研,“日收益率”和volume成交量的关系。成交量作为横坐标,日收益率为纵坐标。
# 想知道,成交量放大时,一般是上涨还是下跌居多?
sh300.plot.scatter(x="volume", y="日收益率")
# 统计,当volume>10000时,上涨和下跌的个数统计
print('成交量均值=', int(sh300['volume'].mean()))
sample = sh300[sh300['volume'] > sh300['volume'].mean()][['volume','日收益率']]
sample.loc[sample['日收益率'] > 0, '正负'] = '正'
sample.loc[sample['日收益率'] < 0, '正负'] = '负'
sample.loc[sample['日收益率'] == 0, '正负'] = '平'
counts = sample['正负'].value_counts()
print(counts)
print('当放量(volume高于其平均值)时,上涨的概率是=', int(counts['正']/counts.sum()*100), '%')
# 如果是上4分位,看一下效果
p75 = np.percentile(sh300['volume'].values, q=75) # q=75,表示计算的数字结果,可以超过 >75% 的样本值
print('n成交量75%百分位=', p75)
sample = sh300[sh300['volume'] > p75][['volume','日收益率']]
sample.loc[sample['日收益率'] > 0, '正负'] = '正'
sample.loc[sample['日收益率'] < 0, '正负'] = '负'
sample.loc[sample['日收益率'] == 0, '正负'] = '平'
counts = sample['正负'].value_counts()
print(counts)
print('当放量(75%百分位)时,上涨的概率是=', int(counts['正']/counts.sum()*100), '%')
成交量均值= 4315678
正负
正 528
负 455
平 10
n 1
Name: count, dtype: int64
当放量(volume高于其平均值)时,上涨的概率是= 53 %
成交量75%百分位= 5304913.0
正负
正 362
负 334
平 8
n 1
Name: count, dtype: int64
当放量(75%百分位)时,上涨的概率是= 51 %
通过计算的结果可见,不管是通过计算均值以上的放量,还是75百分位以上的放量,上涨的概率都不高。(这个针对沪深300而言的结论)
1.1.5. 线性回归模型拟合sns.lmplot
这个听起来比较高大上,实际就是一个函数的运用,类似于在K线图上划线,有点经验的老司机应该都是能画出来的,而且更有的放矢。
后面还会针对这个,更进一步分析我们的划线y=ax+b,其中的a、b的计算方式。
再之后,还会尝试通过手动划线(知道2个点,计算其直线的斜率,再换算为年化收益率,这才更有所谓的底。)
import seaborn as sns
import pandas as pd
import ssl # # URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1091)>
ssl._create_default_https_context = ssl._create_unverified_context
sh300 = pd.read_csv("https://gitee.com/kelvin11/public-resources/raw/master/510300.csv", parse_dates=['date'], index_col='date')
sh300['day'] = np.arange(0, 2819, 1)
sns.set_style("white")
gridobj = sns.lmplot(x="day", y="close", data=sh300,
ci=95, scatter_kws={'color': 'orange'}, line_kws={'color': 'green'}, markers='o')
1.1.6. 皮尔森相关性系数sns.jointplot

import pandas as pd
import seaborn as sns

import ssl # # URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1091)>
ssl._create_default_https_context = ssl._create_unverified_context
stock_index=pd.DataFrame()
sh300 = pd.read_csv("https://gitee.com/kelvin11/public-resources/raw/master/510300.csv", parse_dates=['date'], index_col='date')
stock_index['510300'] = sh300['close']
sh500 = pd.read_csv("https://gitee.com/kelvin11/public-resources/raw/master/510500.csv", parse_dates=['date'], index_col='date')
stock_index['510500'] = sh500['close']
# print(stock_index)
#计算这些股票指数每日涨跌幅(第0行的数据不要了:2012-05-28是无法计算的,之前没有数据)
tech_rets = stock_index.pct_change()[1:]
# print('收益率:n', tech_rets)
#jointplot这个函数可以画出两个指数的”相关性系数“,或者说皮尔森相关系数
sns.jointplot(x='510300',y='510500', data=tech_rets)
# sns.pairplot(tech_rets.iloc[:,:].dropna())
plt.show()
结果如下图。可见:510300和510500,基本是属于正相关的。同时也可以看出,这个图,是一个定性的描述,我们还可以通过其他方式计算出相关系数,并画出热力图heatmap。就是下一例。

df.rename(columns={'close': stock['name']}, inplace=True) # 用股票的名字来重命名close列
if df_all.size == 0:
df_all = df
else:
df_all = df_all.join(df) # join是按照index来连接的。
# df_all.dropna(how='any') # 计算相关性的时候,应该是已经去掉了NaN。这一句,加不加,效果一样
# Plot
plt.figure(figsize=(12,10), dpi= 80)
sns.heatmap(df_all.corr(), xticklabels=df_all.corr().columns, yticklabels=df_all.corr().columns, cmap='RdYlGn', center=0, annot=True)

通过下图可以看出,如果追求极致的负相关,应考虑新能源和黄金。不过一般我们可能主流投资沪深300,那找沪深300的负相关,应该最佳是房地产ETF,不过还是要根据自己的实际情况来选择。
比如如果选沪深300和中证500,他俩相关系数是0.81,相关性还是很高的。
